Research On Workflow Engine And Rule Engine Based On SaaS

With the rapid development of Internet and the gradual maturity of SOA, SaaS has become a popular software service mode. Software as a Service is an important trend for future software development, the traditional process engine and rules engine began to not meet the requirements of the current enterprise business, as company increasing types of service-oriented business, Workflow engine and rule engine as a service to be an inevitable trend.Service-oriented Workflow engine will provide a better function of Workflow management for service-oriented applications and more convenient to build types of applications by using service-oriented applications. Using service-oriented rules engine to separate business rules from business processes will effectively improve configurable and flexible of business applications.This paper discusses the current research status of Workflow engine and rules engine, and the related implementation techniques of SaaS, and its basic infrastructure-cloud computing. Then study these advantages and difficults with traditional techniques and discuss the telecom operator's advantages and initiatives on Cloud computing.On the basis of the above, I build the service model of Workflow engine and rule engine on the SaaS by using service-oriented analysis and design methods, and describe the service functions in the model, which have some reference values for building SaaS Workflow engine and process engine, and then I put forward the method of making existing software as a service. It is beneficial for the existing engine and other existing software as a service, so it will help enterprises from the traditional delivery model to SaaS delivery model. Then analysis the operation and storage characteristics of the Workflow engine and rules engine on the SaaS mode and the implementation of Multi-Tenant, at the last, I design and imply the SaaS Workflow engine based on the SaaS process service model, which verify its feasibility.
